500 internal server error caused by Jetpack

Hi,
since this morning I’m getting a 500 error when opening 1 page (and its sub-pages). I’ve figured out that the Jetpack plugin is causing it but have no clue how to fix it.

I’ve not changed anything on the page in the past days and can’t remember if I’d just updated Jetpack or not.

Please help!

Linda
